Zoa Plugs from Gorilla Glass are beautiful and unique pieces. Their colouring is subtle and they have a very unusual grain which makes them stunning eyecatchers. Since the jewelry is made from glass by hand each piece of jewelry is unique. No grain is ever the same which gives each Zoa Plug its own individual character. They are available in 12, 14, 16, 19, 22, 25 and 32mm.
